For the free apps I use Google Maps a lot, way better than Apple Maps for my area. I also have T-Life installed because T-Mobile is the cell phone service I have but only need the app on occasion. (Later he mentions thinking T-Mobile was in 3rd place for subscribers and seemed surprised. All I can say is he must not travel into the rural west. There is basically no service from Verizon over vast swaths of the western US. The only carrier that is likely to have service in smaller towns is T-Mobile and some of them have ATT. Our nearest Verizon tower is about 11 miles away and behind a hill for much of our area.
Of the paid apps the only one that is close is I have the Skyview Lite free version and use it occasionally. So not paying for it.
